Q1. A 53.5 g Super Ball travelling at 26 m/s bounces off a brick wall and rebounds at 21.50 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 4.25 ms, what is magnitude of the average acceleration of the ball during this time interval?

Q2. A 131 kg sign hangs between two buildings by two cables. Cable 1 is attached at a 36 degree angle wrt to the horizontal, and Cable 2 is attached at a 24 degree angle wrt to the horizontal. What is the tension in cable 1?
